kad-telemetry v0.0.1

Kad Telemetry

Framework for analyzing network behavior and performance for Kad.

Installation

npm install kad-telemetry --save

Quick Start

Decorate your transport adapter.

// Import dependencies
var kad = require('kad');
var telemetry = require('kad-telemetry');

// Decorate your transport adapter
var TelemetryTransport = telemetry.TransportDecorator(kad.transports.UDP);

// Create your transport instance
var transport = new TelemetryTransport(contact, {
  telemetry: { filename: 'path/to/telemetry.data' }
});

You might also like to extend Kad's peer selection by scoring peers based on the collected metrics by decorating your router.

// Decorate the default router
var TelemetryRouter = telemetry.RouterDecorator(kad.Router);

// Create your router instance
var router = new TelemetryRouter({ transport: transport });

Then create your Kad node and party.

// Create your node
var dht = new kad.Node({
  router: router,
  transport: transport,
  storage: kad.storage.FS('...')
});

Once you have been connected to the network, you can lookup a node's profile.

transport.telemetry.getProfile(contact);
// Example profile:
// This node has a ping of 54ms and has responded to 5 of 6 requests
//  { metrics: { latency: 54, availability: [6, 5] } }
